iOS: Cydia themes designer Adam Insull has shared a giant list of all the jailbreak/Cydia tweaks that are compatible with iOS 6. (There's an unofficial method to jailbreak iOS 6 with redsn0w out now.) Check out the shared doc to see what tweaks you'll be able to use on a jailbroken iDevice.

The list includes everything including if the tweak is working or not, notes, and price. Currently, 235 tweaks are listed.

If you find any others or have corrections, you can email Adam (his email is in the spreadsheet).
